Sr Embedded Software Engineer (Sandy, UT - Hybrid)

Since 1985, Digi International has been a pioneer in wireless communication, forging the future for connected devices and responding to the needs of the people and enterprises that use them. Before the Internet of Things was a thing, we built M2M and IoT devices, adapted to evolving network standards, and optimized data communications around the most advanced protocols and emerging technologies. From radio frequency modems to gateways, cellular routers, networking devices, embedded system-on-modules (SOM) and single-board computers (SBCs), Digi's solutions have continually grown to serve an extensive breadth of applications across the IoT landscape. Today, our IoT offerings include sensor-based solutions, a sophisticated platform for remotely monitoring device deployments of any size, anywhere, as well as professional design, implementation and certification teams to help you carry out your vision, no matter how large or small.

Position

Digi International is looking for a Senior Embedded Software Engineer to design, develop, and debug embedded firmware for Silicon Labs–based modules within the Digi XBee family of wireless products. This role will contribute to both sustaining engineering and new product development, working on low-level hardware interfaces, RF-enabled systems, and next-generation wireless solutions. The ideal candidate will bring deep expertise in C-based embedded development, hands-on hardware debugging experience, and the ability to thrive in a collaborative Agile environment while mentoring junior engineers and helping drive technical excellence across the team.

What You Will Do

• Develop, integrate, and debug embedded firmware in C on Silicon Labs-based modules as part of the Digi XBee family of products
• Design and implement low-level hardware interfaces, peripheral drivers, and platform abstractions for new and existing XBee products
• Use laboratory and embedded debug equipment—including spectrum analyzers, oscilloscopes, logic analyzers, and JTAG/SWD tools—to troubleshoot firmware, RF behavior, and system-level issues
• Maintain and enhance existing XBee products through sustaining engineering, including customer issue investigation, defect resolution, and long-term codebase support
• Contribute to the development of new, leading-edge wireless products that expand Digi’s XBee portfolio and roadmap
• Collaborate closely with cross-functional teams (hardware, QA, product management, and manufacturing) to ensure high-quality product delivery
• Participate actively in a SCRUM / Agile development environment, including sprint planning, estimation, daily standups, and retrospectives
• Mentor and provide technical guidance to junior engineers, including code reviews, design feedback, and best-practice coaching

Who You Are and What You Bring

• Minimum of 10 years of professional experience developing embedded firmware in C for bare-metal and RTOS-based systems
• Proven ability to design, implement, and maintain low-level firmware interfacing directly with hardware
• Strong experience developing hardware abstraction layers (HALs) and device drivers
• Extensive hands-on experience with serial communication protocols, including SPI, I2C, UART, and related interfaces
• Solid understanding of embedded system architecture, memory constraints, timing, and real-time performance
• Demonstrated experience working with RF communication protocols and wireless systems
• Ability to independently analyze requirements, architect solutions, and drive development from concept through production
• Experience collaborating within a SCRUM / Agile development environment
• Strong debugging skills using oscilloscopes, logic analyzers, JTAG, and other embedded debug tools

Desired But Not Required

• Experience developing tools, automation, or test infrastructure using Python
• Familiarity with wireless standards such as Wi-SUN, Zigbee, Bluetooth, Sub-GHz, or similar RF technologies
• Experience supporting products through the full lifecycle, including sustaining engineering and customer issue resolution
• Prior experience mentoring junior engineers or acting as a technical lead
